JavaScript does not support function overloading, but there are workarounds. Learn what function overloading is, why it is not supported in JavaScript, and how to achieve similar results using other techniques.

JavaScript may not support Function Overloading, but we can simulate the behavior.

In other languages, an overloaded function can be created by adding another function with the same name. This can’t be done in JavaScript because the 2nd function will overwrite the 1st function.

One method of simulation this behavior is to detect the function argument types.

NOTE: The code does not consider null as an argument and will error if null is received. To prevent this error use this if statement to also check for null.

if (typeof x === 'object' && x != null)
